In Small acaulescent Palms the stem is apparently absent and subterranean or too short to be conspicuous and the leaves are less than 2 m long.
While the percentage of Small Palms species is not different from the percentage in the overall species growth-form spectrum, Small acaulescent Palms are under-represented (P<0.
Description of the genus--Solitary or caespitose, acaulescent or stemmed, spiny, pleonanthic, monoecious palms.
This subsection brings together solitary or caespitose, medium-sized to large, or subacaulescent, or acaulescent palms, all of them with large leaves (4--8 m long), and two slender species with leaves 2--3,5 m long and a stem up to 3-4 m in height and up to 15 cm in diameter.
Mortality is high before the acaulescent juvenile stage, which is in general highly resilient.
Palms with a long, acaulescent establishment phase, and a long subcanopy to emergent reproductive phase, tend to have a U-shaped population structure due to the accumulation of juveniles and adults and the scarcity of subadults in phase of rapid trunk growth (Vallejo et al.
For example, around Iquitos in Peru, there are three acaulescent species with pinnae regularly arranged and spreading in one plane, which key out as Attalea racemosa, Attalea microcarpa and Attalea butyracea in Henderson's Palms of the Amazon (1995), and as Attalea ferruginea, Orbignya polysticha and Scheelea plowmanii, respectively, in Glassman's (1999) monograph.
Henderson (1995) considered also the acaulescent A.
Low or acaulescent palms offer the best conditions for management, as their harvest does not require great effort or special tools, and thus, damage to palms is minimized, requiring only regulation of harvest volumes and times for guaranteeing sustainability.
